About this map

Helena and the industrial corridors of the Missouri River anchor the western edge of this 1947 compilation, where the transition from valley floor to the high timber of the Helena National Forest is sharply defined. The map records a critical era for the region's water infrastructure, capturing the presence of the Canyon Ferry Dam and the Hauser Dam, which transformed the river into a sequence of reservoirs including Canyon Ferry Lake and Lake Helena.

Further east, the cattle and mining country of Meagher County is mapped in detail, centered on the historic hub of White Sulphur Springs. The landscape is etched with the routes of the Chicago Milwaukee St Paul and Pacific and the Northern Pacific railroads, which facilitated the movement of goods through mountain passes like those near Ringling and Maudlow. The network of primary routes, including U.S. 91 and U.S. 12, connects smaller settlements such as Radersburg and Toston to the capital and the burgeoning valley markets.
